Application filed December 27, 1915. Serial No. 68,769.

To all whom it may concern:

Be it known that I, IRviNo F. AVERY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Wagons or the i like, of which the following is a description.

is increased" rather than decreased.

My invention belongs to that general class of devices known as dump wagons, and relates particularly to a wagon or truck having a body arranged to be tilted or elevated so as to discharge the load at a desired point in a minimum time and with a minimum of labor. The invention more particularly relates to improved mechanism for tilting the body or lowering it back to carrylngposition. The invention has among its objects the production of a device of the kind described that is simple, convenient, durable, eflicient and satisfactory, that may be used wherever found applicable. The invention also includes an improved form of body arranged to normally inc-ase the hoisting mechanism and protect it against injury or against action of the elements, the construc- 7 tion being such that the capacity of the body Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and com- 'bination of parts herein shown and described, and more'particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Referring to the drawings, 1 represents the vehicle frame or chassis supported by wheels 2 and 3, or their equivalents for the purpose. It may be mentioned in this connection that while a four-wheel truck is shown, the forward end of the chassis frame might be suitably carried from a tractor or truck, the same constituting a trailer, or the vehicle might be merely a four-wheeled trailer to be drawn *by a tractor truck or other motive power. Arranged on thelvehicle is a body 4, which is carried by the supporting frame parts 5 and cross beams 6. The body and ts frame are suitably pivotally or tiltably carried by the vehicle. In the construction shown the body frame are pivotally supported and secured to the vehicle frame at 7. It is, of course, obvious that any style or type of body 4 may be employed, that shown being merely for illustration.

In the preferred embodiment of the invention, the body is elevated or lowered, by means of a hydraulic hoist, which is pivotally carried from the frame 1, aswill be hereafter described.

-The hydraulic hoist shown consists of an outer casing 8, from the top of.which projects a plunger rod 9. The hydraulic casing 8' is supported on the frame 1 by the cross beams 10 and 11 (see Fig. 6). As shown, brackets 12 are supported on the base piece 10, and the angle 13 carried by the beams 10 and 11, the several parts being secured together in any desired manner. The casing 8 is formed with a T-shaped lower end terminating in trunnions or bearings 15. The casing or cylinder may be connected with the pumping mechanism in any suitable manner. Extending through one side of the base trunnion (see Fig. 7) is a duct 16, communica in the casing 8, at the lower side of the plun er 18, which carries the plunger rod 9. T e duct 16 is connected by means of pipe 19, orthe equivamechanism. It will be noted that the two" point is merel pipes 19 and 21 being connected-at the base,

as shown, the movement of the hoist at that pivotal .or rotatable. The pipes are suita ly connected to the base in any preferred manner, so that the hoist is free to tilt or pivot without movement of the pipes, suitable stufiing boxes being employed. It is not considered necessary to illustrate or describe in detail the stuflingboxes, as these may beas preferred, as long as they are suitable for the purpose, and in case flexible conductors are used connected to the casing, the stufling boxes would not be required at the base.

Arranged at the upper end of the plunger 9 is a head 25, which is formed with shaft ends 25', upon which are arranged the sheaves or pulleys 26, over which extend the cables 27, or their equivalents. end of each of the cables 27 is secured to the brackets 2 8,"which are suitably secured to the beams 6 at the front of the body or its frame. The cables 27 may be provided with terminals 29 (see Fig. 3) for convenience in fastening the same to the brackets 28. The opposite ends of the cables are suitably connected to the vehicle frame 1, or the equivalent. As most clearly shown in Fig. 8, cables 27 are connected to a bar 30, and this is connectedby means of rod 31, 3'2; and turnbuekle q33 to a bracket 34, secured to the'c-ross-beam 11. (See Figs; 6 and '8). The turnbuckle permits adjustment of the parts. Asis obvious, as the'plunger 18 is raised, raising .thejplunger rod 9. and head '25, the forward end of the body, to which is secured one end of each of the cables 27, is raised, the opposite ends of the cables being fixed at the base of the hoist. "The head.

25 is suitably connected with the body, as will be hereafter described, so that as the body is raised, the "hoist is tilted with and-toward it, for the reason mentioned.

Arranged at the rear of the hoist, and at the forward end of the body 4, is a barrier.

or wall '36, the same .being' preferably provided with sides 37 and top 38, the same forming a casing or housing about the hoist -when the body is down, as shown in Fig. 1.

It is not necessary, however, for the housing to be the full width of the body;'consequently the sides of the body may be extended to the forward end of the housing, and the cross wall or end partition 39 provided. This affords considerable additional 'carryingspace at each side of the hoist, and

at the same time the hoist is practically One .the plunger rod 9.

be partitioned, so that the forward end of the hoist is inclosed when the same is in the position shown in Fig. 1.

As most clearly shown in Figs. 1, 2, 3, 4 and 5, arranged within the housing and carried by the Wall 36 are a pair of'guides 40, or their equivalents, it being readily understood that channels or the equivalent would serve the purpose of the I beams shown. The head 25 carries rollers 42 arranged to co-act with the guides, and, as shown, it is formed with extending parts 41, carrying a shaft 43, upon'which are arranged the rollers 42, or their equivalents, arranged to engage with the beams or guides 40. The guides 40 shown are preferably curved slightly backward at the upper end in some cases (as shown) and in other cases at the bottom, or at both top and bottom, so

that the hoist stands substantially vertically when the bodyis down and works smoothly. This, however, is a matter of design, depend ing upon the sizes and construction of the parts, etc., as in some cases straight guides the pump or the equivalent is operated so as to raise the plunger 18, or its equivalent, the head 25 is raised, owing to movement of p The head being raised and'the ends of the cables 27 being secured to the vehicle frame, as previously described, the length of the part of the cables between the brackets 28 and the sheaves 26 is shortened, causing the body to be raised. As the forward end of the body rises, it draws the head 25 over, tilting the hoist. The object and advantage of the tiltin of the hoist may: best be understood by referring to Fig. 5. Referring to this figure, it will be the endsof the cables 27 and the plunger rod9 aresubstantially parallel at all times;

consequently all power ap lied is utilized for moving the load wit out transverse strain on the hoist. To drop the body the hydraulic mechanism is controlled so'that the plunger settles back, the weight of the body causing it to drop, and at the same time move the hoist back to vertical position.

A slightly modified construction of device is shown in Figs. 9, 10 and 11, the difference being in the mechanism for tiltin the hoist simultaneously with the tilting o the body. Referring to these figures, 46 represents the vehicle frame pivotally carrying the body 47, only a portion of the body and vehicle being shown. The casing 48 is pivoted to the frame at 52 similar to the other construction, 49 being the plunger rod carrying the head 53. The cables 51 extend over the sheaves 50, and in so'far as described the device is similar to the other construction. In this case, however, guides 56 are arranged on the side of the casing 48, and arranged to slide on the guides are blocks of any suitable design. These blocks are connected with the head 53 by the bars 54:, and connected with the vehicle frame by bars 58, the same being pivotally secured to the blocks by the bolts 57, and to the frame 'at 59. With this construction as the head 53 is raised it raises the blocks '55 through the rod 54, thereby raising the forward end of the bars 58. As these are raised the same draw the casing 48, or, that is, draw the hoist to aninclined position, so that the pulling or strain on the cables 51 is parallel with theplnnger 49. The blocks 55 may bemaintained on the guides by passing a bolt through the bars or members 58, as shown, or in an equivalent manner.

As before stated, it is immaterial upon what style of truck or vehicle the hoist is mounted, and it is likewise immaterial as to the particular style of body carried upon it. With either construction there isno bending or transverse strain on the hoist. It will be noted by referring particularly to Fig. 1, that the forward end of the. body 4 may extend up close to the cab in this construction. Ordinarily the bodies are cut off substantially at a point in alinement with the wall 36 of the hoist housing. I have not considered it necessary to illustrate in detail any of the hydraulic apparatus, such as the pump or method of controlling the same, as any style of pumping mechanism or the like may be employed.

Having thus described my invention, it is obvious that various immaterial modifications may he made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction. arrangen'ient or combination of parts herein shown and described, or uses mentioned.
